Paper Abstract

1.06-micrometer Nd:YAG laser as well as 1.5-micrometer Yb:Er:glass one under transversal pulsed diode pumping are considered. At free running mode maximum slope efficiency was 31.5% and 31% respectively. Excellent short-term stability of the output energy was demonstrated. In series of few tens of pulses the standard deviation was less than 0.03%. It is shown that noise of pumping radiation practically does not influence on spiking of Yb:Er glass laser radiation, while it may strongly influence on spiking of Nd:YAG laser. Strong influence of weak reflection of laser radiation from an extra- cavity surface on spiking of Er:glass laser is observed. A conclusion is made that the radiation is rather coherent. Tuning of Er:glass laser spectrum within about 4 nm is obtained at low variation of output energy. Splitting of 1535- nm spectral line into several components is observed.
